There's a reason that Genesee Mountain Park is a favorite destination for field trips by schools in and around the Denver area: It could hardly be more kid-friendly. Because Interstate 70 runs through it, Genesee is really two parks in one, with the portion south of the highway including Genesee Mountain, whose summit provides an unobstructed view of the area but at 8,284 feet isn't overly intimidating. The same is true of 7,988-foot Bald Mountain to the north. Elsewhere, the park offers relatively gentle elevation changes, trails that third-graders can handle, and a herd of bison that give members of the younger generation a feel for the Old West.
